SYRINGE Filed sept. 14. 1929 Patented Apr. 14, 1931 PAUL B. VALLE, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO'TI-IE MARVEL COMPANY,

F NEW HAVEN, CONNECTICUT SYRINGE Application filed September 14, 1929. Serial No. 392,604.

My invention relates t'o a syringe, and more especially to a douche syringe of the injection and suction type. Syringes of the type contemplated comprise generally speaking a relatively large soft' rubber bulb, to which is connected a nozzle, the latter being provided usually with means for breaking up the liquid discharged from the syringe into a number o-f fine streams or j-ets, or into a whirling spray, in order to bring about a more eective cleansing of the vaginal passage.

It is, in general, an object of the invention to provide a syringe of the above type in which the cleansing of the vaginal passage may be more efficiently carried out than in syringes as heretofore known.

A further object of the invention is to provide a syringe in which the danger of injury to the internal organs is greatly reduced.

In a more specific aspect, itis an object of Athe invention to provide a syringe in which the stream of liquid discharged from 'the nozzle conforms in shape to the shape of the vaginal passage.

To these and other ends, the invention consists in the novel features and combination of parts to be hereinafter described and claimed.

In the drawings,

Fig. 1 is a general view showing a syringe according to my invention;

Fig. 2 is a cross-sectional View of the nozn zle ofthe syringe shown in Fig. l, but on an enlarged scale;

Fig. 3 is a view similar to Fig. 2, but shows ing the direction of movement of the liquid discharged through the end of the nozzle; and

Fig. 4l is an end view of the nozzle.

Referring to the drawings in which 1 have illustratedv my invention by showing a preferred embodiment of the same, the reference numeral 10 indicates, in general, the improved syringe which comprises a collapsible bulb 11, preferably made out of soft rubber and having a neck 12 in which one end of nozzle 13 is received, the end of nozzle 13 being provided with a groove, as at 14, forA the reception of neck 12. Adjacent the bulb 11, nozzle 13 is provided with an enlarged part or shield 15 which when the syringe. is in use serves to prevent the escape of liquid and to ensure the return of the latter to the bulb. Nozzle 13 is provided with an internal bore 16, which is threaded at 17, for the reception of a tip 18, tip 18 being provided with threads 19 for reception in the threaded end 17 of nozzle 13, with an axial bore 20 and an enlarged chamber 21 in which is received a deflector 22, the outer end of tip 18 being flanged, as at 23, to prevent the delector from becoming dislodged from the chamber 21. Deflcctor 22 is provided with a number of axially directed vanes 24, which are inclined at an angle to the axis of the bore 20, and which when liquid is discharged through passage 21, serve to impart a whirling motion to the liquid.

1 have found that when the cross-sectional area of the bore of the nozzle adjacent the deflector is less than the sum of the cross-sectional areas between the vanes on the deflector that the liquid isrnot only given a whirling action as it is discharged from the nozzle but is caused to assume an ellipsoidal shape, as shown in Fig. 3 of the drawings, the ellpsoidal shape of the stream conforming in shape to the shape of the vaginal passage adjacent the end of the nozzle' when in USC.

It will be readily understood that as the liquid is caused to assume a shape in conformity with the shape of the vaginal passage, all parts of the latter are reached by the jet, resulting in a more eflicient cleansing of vthis passage than has heretofore been possible without, however, any dangerof injury to the organs reached by the et'.

While I have shown a preferred embodiment of my invention, it will be understood El U that it is not to be limited to all the details through which a liquid may pass to be dis V charged in a jet,y said nozzle being provided in the outer end thereof with an enlarged chamber, and a deflector mounted in said' chamber, said defleetor being provided with a plurality of radially directed Vanes, the cross-sectional area, of the bore of the nozzle inwardly of the deflector being less than the sum of the cross-sectional areas between the venes.

In witness whereof, I have hereunto set my hand this 11th day of September, 1929.
